Abstract

Fertilizing field experiment was carried out at the Experimental Station of Aleksandras Stulginskis University in 2014–2015. Spring rape and spring barley with under-crop, perennial grass in the 1st year of use, and winter wheat were grown in four-field crop rotation. The experiment aim was to evaluate the influence of fertilizer on spring barley and on oilseed rape applying bioorganic nanofertilizers (BNF) and N60P60K70. The spring barley breed ‘Luokė’ and the oilseed rape ‘Sponsor’ were grown for the experiment. The research showed that N60P60K70 and BNF had a positive effect on the yield of spring barley ‘Luokė’ and of oilseed rape ‘Sponsor’. The spring barley grain yield increased from 6.8 to 16.3% and the oilseed rape seed yield increased from 8.1 to 23.3% compared to the control. The best yields were obtained fertilizing with N60P60K70 and BNF rate 1.0 l ha–1 and spraying twice. Fertilization with N60P60K70 and BNF 1.0 l ha–1 sprayed twice increased the crude protein content in grains by 0.51%. Fertilization with N60P60K70 and BNF solutions significantly increased the yield of spring barley grain and straw and improved the grain quality, positively influenced 1 000 grain weight, sprouting energy and germination. Application of N60P60K70 and BNF for barley is economically beneficial because it gave the highest profit compared to other options, 158.10 € ha–1. The premium yield of spring rape, sprayed with BNF 1.0 l ha–1 solution twice, was higher by 89.92 € ha–1 than that of the oilseed rape sprayed once. Application of N60P60K70 and BNF on oilseed rape is economically beneficial because it gave the highest profit compared with other options, 172.90 € ha–1.
